What is ADABAS?
« on: October 16, 2008, 03:54:52 PM »
ADABAS (acronym for Adaptable DAta BAse System[1]) is Software AG’s primary database management system.

ADABAS is an inverted list database. It has been described as "Post-relational" but “Relational Like" in its characteristics. Some differences:

    * Files, not Tables as the major organizational unit
    * Records, not Rows as content unit within the organizational unit
    * Fields, not Columns as components of a content unit
    * No embedded SQL engine, an external query mechanism must be provided.
    * Search facilities may use indexed fields or non indexed fields or both.
    * Supports two methods of denormalization: repeating groups in a record ("periodic groups"); and multiple field values in a record ("multi-value fields").

It has proven to be very successful in providing efficient access to data and maintaining the integrity of the database. ADABAS is now widely used in applications that require very high volumes of data processing or in high transaction online analytical processing environments.
